Rotary UPS Systems

A rotary or ‘flywheel driven’ UPS carries the server equipment for short duration outages of 10 – 50 seconds dependent on the load being supported. This system works in conjunction with a standby generator, which will power up and receives the critical load within this time period. A rotary UPS also supports the server load through voltage dips, etc…

A rotary UPS may be installed in lieu of a battery back-up UPS system or in conjunction with one.The Rotary system will support the critical load in short durations and until the load transfers to generator. The battery back-up system would then support the load upon failure of the rotary system to engage or the generator to start.
